Everyone has a story, even Kreacher the ill-will house elf. Here, in chapter ten, we learn the extent of creature’s involvement in the hiding of the horcruxes at the hand of Voldermort. Truly, Kreacher is an example of slavery at its basest. He is a servant to both the Dark Lord, and Regulus and Sirius. He seems to be torn between his instinctive loyalty between the three. The one who has treated him the worst was actually Sirius. It was Regulus who sacrificed himself and looked out for Kreacher’s safety, even as he died beneath the water in the cave. Kreacher is left with a sad story and a torn up conscience, which explains his demeanor to this point.
